 ==Lamp Alignment==
-Whenever you put in a new xenon lamp it must be properly aligned on the X, Y and Z axis (horizontal, vertical, axial) to have even illumination and achieve the proper luminance on screen. Poor lamp alignment can result in hot spots of light on screen, damage the reflector, lens, and even the print. A lamp alignment should be performed when a new lamp is installed and periodically thereafter because the position may drift over time.

 Lamp alignment should be done whenever a new lamp is installed, if you see hot spots or shadows on screen, film prints exhibiting embossing or burns, or if you are switching between different [[Film gauges]] on the same projector.
